RESET:
The RESET bit implements a software reset. If the RESET bit is a logic 1, the OCTLIU is
held in reset. This bit is not self-clearing; therefore, a logic 0 must be written to bring the
OCTLIU out of reset. Holding the OCTLIU in a reset state effectively puts it into a low-power,
stand-by mode. A hardware reset clears the RESET bit, thus deasserting the software reset.
TYPE:
The device identification bits, TYPE[2:0], are set to a fixed value of “100”
ID:
The version identification bits, ID[3:0], are set to a fixed value representing the version
number of the OCTLIU.
